In one of the new PSA 48V MHEV, it says among other things: Quotation: Two power grids The PEUGEOT 3008 and the PEUGEOT 5008 have two power grids: a low voltage grid with 12 volts for the supply of the vehicle equipment and a high voltage grid with 48 volts for the supply of the hybrid system. The electricity is generated exclusively by the 48V electric motor. A DC voltage converter transfers the generated electricity into the 12-volt network of the vehicle. This leads me to the question: Is there another 12V alternator? On the product picture (in the appendix) it looks like for me that the belt of the auxiliary units drives an alternator in addition to the climate compressor.
